on bare metal if you use on xfce a conky and have it setup to start up automatic , you wil see something very strange if you use a dual screen , logout of xfce and login in i3 ok ...
than logout of i3 and back login in your xfce , and take a look where the position is of your conky out of range , that is not good at all baby ..

its very strange behaiver that i never seen before in a linux distro , for the rest works fast , but this are only things you wil see on bare metal not in virtualmachine
